Abstract (en)
Device for distributing and dispensing liquid within a water treatment unit containing a filter material, characterised in that it includes especially a tray (1) separating the treatment unit into an upstream zone (5) containing the filter material (7) and a downstream zone (6) provided with at least two separate parts forming distribution networks, one of them being pierced with a plurality of orifices (2, 3) which allow the treated fluid which has passed through the filter material (7) to flow between the upstream zone (5) and the downstream zone (6), which communicate, by means of a distribution orifice (11) which can be shut off as a function of the direction of flow of the fluid, with the second part of the said tray and the network for removal of the treated fluid, the additional part (8) being furthermore provided, on one of the faces of the tray, with a plurality of openings (2, 3) which permit a flow of the regenerating fluid within the said filter material during the regeneration stage, the said regenerating fluid being introduced via the network for draining off the treated fluid.
